Dreams, machines and music can take us to the far reaches of our imagination. SPACECRAFT, the group, launched it's CD debut in 1997 with a critically acclaimed self-titled CD on the small and independent, European/American, Lektronic Soundscapes record label. Billboard gave their next release, "Hummel", a Critics Choice review in 1998. "Earthtime Tapestry" was named "1999 Electronic Album of the Year" by New Age Magazine. The next project landed Tony Gerber, Giles... Topic: SPACECRAFT

A drawing of the VR-190, the first Soviet conception of a piloted spacecraft in the post World War II era. Conceived by Mikhail Tikhonravov at Scientific Research Institute No. 1 (NII-1) in 1945, the VR-190 would carry two "stratonauts" strapped in an upright position on a 200-kilometer "hop" into the upper atmosphere. Many design innovations from the project were later used in the 1060s-era spacecraft, such as Voskhod and Soyuz. Publication information: Image from the files...

A METHOD IS DESCRIBED FOR THE PASSIVE LOCATION OF AN ULTRASONIC SIGNAL GENERATED BY A SPARK IN THE CHAMBER ELECTRODE. THE MATERIALS EMPLOYED AND THE CIRCUIT DIAGRAMS ARE PRESENTED. Topics: SPACE STATIONS, SPACECRAFT DESIGN, SPACECRAFT MODULES, MISSION PLANNING, SPACECRAFT COMPONENTS
After the hatch "Liberty Bell 7" opened prematurely, gallons of seawater entered the spacecraft. A helicopter recovery team attempted to empty the water, as seen in this photo. Seconds after this picture was taken, the Marine helicopter dropped the spacecraft because it was too heavy to continue lifting, and the capsule sank to the ocean floor. Astronaut Virgil I. Grissom was still in the water at the time, and his head is seen bobbing next to the capsule. Grissom almost drowned, but...

Before the first astronaut was launched into space, scientists and engineers had to determine if it was even possible for the human body to function in zero-g. This video reviews some of the instruments and techniques developed at the NASA Johnson Space Center’s Life Sciences Directorate. Included are some of the early tests which were conducted, such as the centrifuge and bed-rest studies, as well as developments in remote medical care capabilities. Also included is a look at the benefits of... Topics: NASA, Manned Spacecraft Center

The wall lining of the chamber consists of successive layers of glass wool panels, of densities 70 kg/cu m and 38 kg/cu m. The former are 80 cm long, the latter, 40, 50, 60 or 70 cm long. The dimensions of the open space in the chamber are: 6.10 m (length) x 4.60 m (width) x 3.80 m (height). The acoustic characteristics of the chamber were examined by measuring the sound pressure level p as a function of the distance r from different sources. The deviations from the decay law are apparent... Topics: APOLLO SPACECRAFT, INTERNATIONAL COOPERATION, SOYUZ SPACECRAFT, DECOMPRESSION SICKNESS, SPACECRAFT...

During the first Galileo flyby of Ganymede, Jovian radio emissions in the frequency range of 700 kHz to 5.6 MHz were completely occulted by the satellite. We take advantage of this serendipitous observation to determine the location of the radio emission source relative to Jupiter. The evidence suggests that the apparent source is along an L greater than or approximately equal to 7 magnetic field line near the central meridian longitude (approximately 160 deg) of the spacecraft and at 1 to 3...

It's no easy task getting Mars Reconnaissance Orbiter ready for launch. Workers stabilize the crane holding one of the enormous billboard-sized solar panels temporarily removed from the spacecraft prior to rigorous testing. This test is one of many "checkups" the spacecraft must undergo to verify its readiness for launch.

Some key components of a NASA-funded instrument being developed for the payload of the European Space Agency's ExoMars mission stand out in this illustration of the instrument. The instrument is the Urey: Mars Organic and Oxidant Detector. It can check for the faintest traces of life's molecular building blocks. If those are present, it can assess whether they were produced by anything alive. It can also evaluate harsh environmental conditions that could be erasing those molecular clues....

One of Viking l's three feet, which should be visible in this view, lies buried beneath a cover of loose Martian soil. This picture, taken Sunday (August 1), is the first to show the buried footpad #3. If not buried, the edge of the foot would be seen extending across the picture about midway between top and bottom. The foot sank about five inches, and fine-grained soil slumped into the depression and over the foot. The cracked nature of the surface near the slump area and the small, steep...

On June 19, 2007, media visited JPL?s newly expanded outdoor Mars Yard where rovers train for future planetary missions. Visitors were treated to a test drive of the ?Scarecrow? rover. Scarecrow might still be missing its computer ?brains,? but it certainly showed off its monster appetite for large boulders, making easy work of traversing them. In early 2008, assembly of this hefty, hyper-capable rover will begin.
